HANDLING THE UNEXPECTEDHANDLING THE UNEXPECTED
n Tire Pressure Monitoring System (TPMS) - Required Federal Explanation
Each tire, including
the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low tire pressure
telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from
functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires
or wheels on your vehicle to ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.

MAINTENANCEHANDLING THE UNEXPECTED
n Inspecting and Changing Fuses
Set the power mode to
VEHICLE OFF (LOCK). Turn off the
headlights and all accessories.
Remove the fuse box cover.
Check the large fuse in the hood.
If the fuse is blown, use a Phillips-head screwdriver to remove
the screws and replace the fuse with a new one. Reinstall the
screws.
Inspect the small fuses in the hood and the vehicle interior.
If there is a burned out fuse, remove it with the fuse puller and
replace it with a new one.
Blown fuse
Combined fuse
Fuse puller
Replacing a fuse with one that has a higher rating greatly increases the chances of damaging
the electrical system.
